Work: Calculate the value of equation 7.5*(1/9%-1/(9%*(1+9%)^20))+100/(1+9%)^20 .
Question type: Mathematical calculation
Solution:
7.5*(1/9%-1/(9%*(1+9%)^20))+100/(1+9%)^20
=7.5*(1/9%-1/(9%*1.09^20))+100/(1+9%)^20
=7.5*(1/9%-1/0.504397)+100/(1+9%)^20
=7.5*9.128546+100/(1+9%)^20
=7.5*9.128546+100/1.09^20
=7.5*9.128546+100/5.6044107677783
=68.464095+100/5.6044107677783
=68.464095+17.843089
=86.307184
Answer:7.5*(1/9%-1/(9%*(1+9%)^20))+100/(1+9%)^20=86.307184
